Permabond UV006490001L0101

UV649 Fast Curing UV-Curable Adhesive, Clear, 1 Liter Bottle

Permabond® UV649 is a single-part, fast-setting, UV-curable adhesive designed specifically for bonding plastics. This material has excellent adhesion to a variety of plastics including polycarbonate as well as metals and glass. Permabond UV649 has very high shear strength, elongation, and impact resistance making it ideal for applications that require substrates with different coefficients of thermal expansion. Permabond UV649 has good depth of curing capabilities which makes it suitable for use as a sealant.

Physical Properties of Uncured Adhesive

Chemical composition: Methacrylate ester
Appearance: Colourless, clear
Viscosity @ 25°C:
- 20rpm: 20,000-30,000 mPa.s (cP)
- 2.5rpm: 80,000-150,000 mPa.s (cP)
Specific gravity: 1.1

Typical Curing Properties

Typical fixture time (acrylic)*
- Low power 4mW/cm² battery lamp: 10secs
- LED 100mW/cm² lamp: 4 secs
- UV light guide 30W/cm²: 2 secs
Cure wavelength 365 - 420 nm**

*The cure time depends on the power of the UV lamp, its spectral output, the distance between the lamp and the components, and the transmission characteristics of the substrates.

**LED UV lamps have a narrow range of spectral output. It is important to check suitability with Permabond to match the LED lamp's peak wavelength with that of the adhesive's photoinitiator to ensure optimal adhesive cure.
